Data store

A data store is a data repository of a set of integrated objects. These objects are modeled using classes defined in database schemas.^[1] Data store includes not only data repositories like databases, it is a more general concept that includes also flat files that can store data.^[2]

Some data stores do represent data in only one schema, while other data stores use several schemas for this task. An example are RDBMS-based data stores like MySQL or ORACLE.

Types

Datastores can be of different types.

• The widely used data store type are relational databases. (Examples: Microsoft SQL Server, MySQL, ORACLE, Postgresql)
• Object-oriented databases, like Caché or ConceptBase. They can save objects of an object-oriented design.
• Operational data stores
• Schemaless data stores, like Distributed data stores (e.g. Apache Cassandra or Dynamo).
